MACHINE FOR MAKING CARTONS.

Application filed October 15, 1923, Serial No. 668,484.

This invention relates to a machine for making cartons, and refers more particularly to a machine designed to cut and score aboxboard stock into the finished form of acarton ready for folding, all part of a continuous operation.

Among the ob'eots of the invention are to provide a mac ine of the character described, in which the cutting and scoring is done by circular dies instead of with the flat die formerly used; to provide a machine of the character described in which time are positioned gripping rolls of small dianr eter forgrippmg the stumped sheet, and driven at a much higher speed than the stamping rolls; to provide a conveyor belt of such width that it permits the waste from the stamped sheet to fall into suitable receptacles, and the stamped sheet itself to [MRS into a separate collector; to provide in a machine of the character described, means for waterproofing the interior of the box with various substances, as for example, parafline; to provide a machine of the char-- acter described in which the stamping means consists of a lower die roll containing knives and punches, and an upper roll containing recesses of predetermined depth, which regu late the scoring and cutting of the blank; to provide a machine of the'character tie-- scribed in which the feeding, stamping, gripping, separating aml collecting'are done automatically as a continuous operation; to provide a machine of the character detimedrelation; to provide a machine of the character described in which the waste from the carton blank will be eparatcd and collected automatically; to provide a machine of the character described which has few working parts and adapted to produce a maximum of stamped forms as part of a continuous mechanical operation.

ing and gripping rolls with certain parts in section.

Fig. 6 is a cross sectional view of the paper guiding means. Figs. 7 and 8 are diagrannnatic top plan views of the stamping and gripping rolls showing the arrangement of the conveyor and the manner of sepa-rat' ing the blanks from the waste.

Referring in detail to the drawings, 1 designates the frame equipped with vertical supporting rods horizontally projecting rod 3 supported by the bar 4. These parts are constructed of steel or other heavy metal. roll of heavy gauge paper 5, is mounted on the shaft (1. which shaft in turn is meant ed on the rollers7, in the arm 3. This papet has been previously prepared in rolls and is of the usual weight suitable for box board manufacture. The paper is fed from the roll 5 through the guide rolls 8, which latter rolls also tend to remore the so called curl of the paper without weakening the fibres, or placing unequal strain thereon.

. The underside of the paper is then coated with a waterproofing material such as hot paralline, by passing over the parafiine bed roll 9, and under the press roll 10. The roll 9 is mounted on the shaft 11 which is driven by the bevel gear 12. the operation of which will be later described. The upper roll 10 is driven in timed relation with the lower roll 9 by means of the gear 13 meshing with the gear 14. proofing material is contained in the tank 15, the contents of which may be heated by the burner 16. It is understood thatv any munncr'of heating the coating may be used, such as steam, etc.

The arrangement is such that the lower roll 9 revolves in the hot par-afline, applying it to the underside of the stock being fed thereto. The stock is then fed through the idler rolls 17 connected to the frame as shown.

We may provide longitudinally extending plates 18 bolted as shown at 19 to the frame and disposed on both sides of the sheet being fed forward. Each plate has inwardly projecting lips 20 for guiding the paper through the machine. The paper is then fed between the stamping rolls 20 and 21 mounted on shafts 20 and 21. The lower die roll 20 (Fig. 4) is provided with a series of knives 22 and punches 23 of, predetermined con- The paratline or other water figurationfi" whichproject from the surface thereof. he punches 23 are spring actuated for ejecting the unched slots from the blank. In the to shown, there are four identical sets of knives on its eriphery, so that one complete revolution 0 the roll will stamp foun forms from the blank. The knives on the die'roll20, whether used for cutting or scoring, are the same height above the face of the roll.

Referring now to the upper roll 21, it is recessed as shown at 23, to register with certain of the knives in the lower'roll. The operation is as follows: At the instant the knives on the lower roll meet the paper to be out where there is no recess in the upper roll, the knife will cut through the paper stock. -Where there is a recess in the upper roll, the knife on the lower roll will not cut, but will press the paper into the depression in the upper roll, thereby scoring it.

As one of the features of-our invention, thestamped sheet is then gripped by the gripping rolls 24 and 25, which latter are revo ving at a much higher rate of speed than the stamping rolls, say, 3 to 1.- It will be readily seen that the gripping rolls, -re-' volving at high speed will grip the stamped sheet and tend to jerk it away from the stampin rolls. This jerkin will have the effect of breaking the sheet where it has been cut, and causing a complete separation between the carton form-and inci ental waste.

This feature is shown detail Figs. 7'

and 8.

After the separation by means of the rollers 24 and 25,,the carton form is conveyed to suitable collecting means, bymeans 'of the endless conveyor belt 26 revolving on the idler shafts 27 and 28. A carton form 29, which has just been formed, is shown (Fig. 7) as passing. between the gripping rolls,

while another form, made just previous to it.

is shown on the conveyor 26, being carried to the collector.

Referring to Fig.8, the belt conveyor is only wide enough to support the main portion of the box being formed, allowing the waste 30 which has just been separated from the carton form 29, to fall intoianyisuitable collecting means." It' will Jrea ?seen that this arrangement allows-"the: oi riied bevel gear 37 meshing with the bevel gear 38.

This bevel gear 38 is mounted on the shaft 40, which shaft terminates in another bevelgg gear 41, which latter meshes with the gear 12 on the shaft 11, drivin the-water proof coating roll 9 and ress r0510 through the gears 13 and 14., he with the gear 43 mounted dlrectly above it on the shaft 21f for driving the upper re cessed' platen roll 21. Thegear 43 in turns; meshes with a smaller gear 44 mounted on the stub shaft 45, which shaft also'carries gear 46. The gear 16 in turn meshes with small gear 47 mounted on the shaft 48. This shaft carries another gear 49 for driving the 'up 'er grippiniroll. The gear 49 meshes with t e car 50, which latter gear drives the lower rol 25 which latter roll in turn drives the endless conveyor belt 26.

Returning ,now to the conveyor. belt 26, the lowergripping roll 25 is recessed transversely asshown at 51 to accommodate the belt 26 from which it secures its drive. The depth and Ten th of the recess is'such that the upper sur ace of the belt when placed in the recess, will be flush with the surface of the roll, andthe edges of the belt substantially touching the inner sides of the recess. (Fig 4.) llhe. gripping rolls .24 and 25 may )e constructed of metal, rubber, etc, and may have their surface suitably roughened to instantly grip the stamped paper as explained.

The shaft 27 driving the lower gripping roll 25 rotates in the side blocks 52, while shaft 53 driving up er gripping roll 24 -rotates in the sideb ocks 54. It will be arrangement is" such that the block 52 will give through the action of the spring 56, thus compensating for any difference in the thickness of the paper stock.

gear 42 "meshes 7e Any variations in the thickness of the paper passing through the stampin rolls 20 and 21 is taken up b means of t e ver tical rod 57 connecting t e split bearin s 58 and 59 in which the shafts'20 and 21 ar. The ends of the blocks 60holding these hearings areadapted to ride in the dovetail portion .61 of the frame.

' We provide a scraper 62 mounted on the brackets '63 attached to the frame, which scraper extends transversely of the roll 21 for removing any 'lint or punched particles of aper which may adhere to this roll.

mm the foregoing, it will be seen that we have provided a noval machine for ducing carton forms, the cartons adapte contain many varieties of materials, such as perishable goods of all kinds. The opera tion is entirely automatic from the roll-of stock to the finished form, and adapted to 0 rate continuously for extended periods 0 time.

We claim as our invention:
